The glass material is more and more popular used for decoration interior and exterior building, like glass window, glass door, glass handrail railing, glass roof, glass skylight, glass curtain wall, etc. Except for the attractive looking, what’s the most you concerned about? For sure is the safety, people’s safety. That’s why heat soaked test glass is a trend. It can be heat soaked tempered glass, heat soaking tempered laminated glass, heat soaked tempered insulated glass. Today let’s talk about the heat soaked glass, hope it can help to know more about it.

What’s the heat soak test glass?Heat soaking is a secondary process to the toughening process. The process involves placing the tempered glass inside a chamber and raising the temperature to 290 ºC to accelerate nickel sulfide expansion. It can help to reduce of the toughened safety glass breaking spontaneously after installation. Therefore reducing the costs on replacement, maintenance or disruption, etc. Compared to the tempered safety glass, it adds cost but carries the risk of reducing the compressive stress in tempered glass.

The process of HST glassFollowing the tempering process, the glass is heated to a temperature of about 290C for 2 hours of the heat-soak period, and then cooled slowly. This process allows the inclusions to revert to their original form and thus regain their stability. In all probability, the glass that have NiS inclusions will break during this heat soaking process, the explosion rate lower than 0.001%. The advantage is to minimize the risks of accidents and injury for humans.
